What harm does listening to music loudly often do to human body?

Don't listen to music too loudly with headphones, preferably not for more than half an hour. Experts remind that a long time will lead to hearing loss and even deafness.

In daily life, we can often see such a phenomenon: some people always listen to music with headphones on the bus, on the road, and even at the bedside. In the music world, they don't listen to things outside the window and look carefree. But when you know what kind of crisis is hidden in these habits that you are most familiar with, will you continue the above actions? When the volume heard by human ears exceeds 85 decibels, it will cause hearing fatigue for too long; When the volume is as high as 1 10 dB, it is enough to kill the hair cells in the inner ear of human body, and in severe cases, it will cause irreversible hearing damage. The volume output of headphones is generally about 84 decibels, and some high-frequency ranges can reach 120 decibels. This volume has a great stimulating effect on the ear nerve. It will cause hearing loss for a long time, and in severe cases, permanent deafness and neurasthenia will occur. Because high-frequency hearing loss first appeared, and the frequency of language used in our daily communication was not affected, it was often ignored in the early stage. Only when the hearing loss reaches a certain level in bass extension and language frequency will there be subjective hearing impairment, which will affect language communication and social activities. So it usually takes many years for young people to see the effects of listening with headphones, so people nowadays generally don't feel the harm, which is what we are worried about.

Nokia Forum: Let's take a look at the structural diagram of the human ear first: if the ear wants to hear sound, natural sound waves must first enter the eardrum through the auricle and external auditory canal, which will first cause vibration of the eardrum. In the middle ear cavity, there are three ossicles, namely the malleus, the incus and the stapes. Sound waves pass through these three bones and then transmit vibration to the cochlea of the inner ear. The cochlea is filled with fluid and connected with hair cells that sense sound frequency. Hair cells that sense high-frequency signals are at the bottom of the cochlea, and hair cells that sense low-frequency signals are at the top of the cochlea. Hair cells can convert the mechanical energy signal of this acoustic vibration into electrical signals, generating nerve impulses, which will transmit sound information to the brain along the auditory nerve, making people feel the sound and finally complete "listening".
